Protner’s cellar starts with a room full of large oval oak barrels their wines mature for at least six months. The next room has stainless steel tanks where a quality wine is stored before offering it on the market. The integral part of the cellar is also Bottle Cellar where wine matures in bottles at a constant temperature.

The cellar has also an older, more than 200 years old, part where Protner keeps the best wine from their own vineyards.

The last part of the cellar is a wine shop where visitors can choose wines that are grown on the Šempeter hills just above Malečnik and around the owners house in Vodole.
